4.2 liters..... there are 1,000 mL in a liter and there is a total of 4200 mL in this case which is divided by 1000 which gives you 4.2 liters.
The equilibrium condition allows finding the result for the force that the chair exerts on the student is:
- The reaction force that the chair exerts on the student's support is equal to the student's weight.
Newton's second law gives the relationship between force, mass and acceleration of bodies, in the special case that the acceleration is is zero equilibrium condition.
∑ F = 0
Where F is the external force.
The free body diagram is a diagram of the forces on bodies without the details of the shape of the body, in the attached we can see a diagram of the forces.
Let's analyze the force on the chair.
Let's analyze the forces on the student.
In conclusion using the equilibrium condition we can find the result for the force that the chair exerts on the student is:
- The reaction force that the chair exerts on the student's support is equal to the student's weight.

Answer:
12 units
Explanation:
This problem can be solved if we take into account the equation for a sphere
![x^{2}+y^{2}+z^{2}=r^{2}\\x^{2}+y^{2}+z^{2}=(\frac{26}{2})^{2}=13^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%2By%5E%7B2%7D%2Bz%5E%7B2%7D%3Dr%5E%7B2%7D%5C%5Cx%5E%7B2%7D%2By%5E%7B2%7D%2Bz%5E%7B2%7D%3D%28%5Cfrac%7B26%7D%7B2%7D%29%5E%7B2%7D%3D13%5E%7B2%7D)
where we took that the radius is 13 units. If we take z=5 and we replace this value in the equation of the sphere we have
![x^{2}+y^{2}+(5)^{5}=13^{2}\\x^{2}+y^{2}=144=(12)^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%2By%5E%7B2%7D%2B%285%29%5E%7B5%7D%3D13%5E%7B2%7D%5C%5Cx%5E%7B2%7D%2By%5E%7B2%7D%3D144%3D%2812%29%5E%7B2%7D)
where we have taken x2 +y2 because if the equation of a circunference.
In this case the intersection is made when we take z=5, for this value the sphere and the plane coincides in values.
Hence, the radius is 12 units
